Building Information Modeling, or BIM, is a method of designing buildings using sophisticated 3D software that makes it much easier to visualize how various components and systems come together in a 3D space and how they will interact or interfere with one another. Perhaps most importantly, BIM facilitates identifying potential conflicts/defects prior to construction, and … Continue reading Pro Tip: BIM doesn’t have to be scary.
